Files reveal BP's worst case spill scenario

Newly released internal documents show BP estimated 4.2 million gallons of oil a day could gush from a damaged well in the Gulf of Mexico if all equipment restricting the flow was removed and company models were wrong.

Democratic Massachusetts Congressman Ed Markey released the documents showing BP said in a worst-case scenario the leak could gush between 2.3 million gallons and 4.2 million gallons of oil per day.
